According to Nasa, meteors are bits of rocks and ice ejected from comets as they move in their orbits about the sun. A meteor that reaches the ground is called a meteorite.
Nasa says meteors are sometimes observed with red, yellow or green trails, caused by the ionisation of molecules like oxygen, which appears green.
There are about 12,000 meteors on any given night that are about the size of a piece of dust.
